| Title | Inhibition of Photosystem II by UV-B-Radiation  | ||
| Abstract | The effect o f UV-B-radiation on PSII activity o f spinach chloroplasts was analyzed by m ea suring the integrity o f the herbicide-binding protein (H BP 32), by m easurem ent o f fluorescence induction in the presence o f Diuron (D C M U), and by m athem atical analysis o f the fluorescence induction curves. It was shown that UV-B inactivates the PSII a-centers but not PSII ^-centers. However, the possibility cannot be excluded that in add ition the donor site o f PSII near the reaction center is attacked by UV-B-radiation. | ||
